Hi Bruce
Thanks for your assistance. I have measured the voltage and I can't get the expected voltage while the buttons are pressed. The only correct voltage I get is with no buttons pressed. However, I have already measured the grounding between connectors, buttons, and encoders and I have a continuity. To what grounding do you refer exactly?
I have carefully soldered all components applying a lot of heat as recommended. Anyway, I can't get the indicated voltage if I push the buttons.
It seems very hard to identify the problem.
